摘要

采用球磨混粉和半固态电磁搅拌的方法制备了石墨烯纳米片（GNPs）增强铝基复合材料

研究了GNPs在复合材料中的分布和形貌;GNPs增强铝基复合材料的微观形貌及力学性能。结果表明

所制得的复合材料中GNPs分布均匀

呈现片状且与基体结合良好;GNPs可细化铝合金显微组织

当GNPs含量为0.6%时细化效果最好

同时复合材料的抗拉强度、伸长率和硬度（HV）到最高值

分别为180.22MPa、5.5%和91.1

比铝合金基体提高了25.3%、243.8%、30.7%。

Abstract

Graphene nanoplatelets reinforced aluminum matrix composites were prepared by ball milling and semisolid electromagnetic stirring.The distribution and morphology of GNPs in the composites prepared and micromorphology and mechanical properties of GNPs reinforced aluminum matrix composites were investigated.The results show that the GNPs in the composites obtained are uniformly distributed

showing platelet-shaped and having agood bonding with matrix.GNPs can refine aluminum alloy microstructure.When the GNPs content is 0.6%

the refinement effect is desirable

moreover

the mechanical properties of the composites reach 180.22 MPa in tensile strength which is 25.3% higher than aluminum matrix.And the elongation and hardness reach up to 5.5% and 91.1 HV.
